SEAL-PRESS.

SPECIFICATION forming part of Letters Patent No. 412,456, dated October 8, 1889. Application filed July 3, 1886. Serial No. 207,056. (No model.)

To all whom it may concern: Y

Be it known that I, CLAUDIUS V. BOUGH- TON, a citizen of the United States, residing at Buffalo, in the county of Erie and State of.

New York, have invented certain new and useful Improvements in Seal-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a partof this. specification.

Myinvention relates to a press adapted especially for compressing the form of seal for which Letters Patent No. 340,758 were granted to me the 27th day of April,1886. The seal covered by such patent was of hollow elongated cylindrical form,within which the ends of the seal-wire temporarily united were compressed, making a permanent union.

My seal-press is an improvement upon that for which Letters Patent were granted to Charles C. Abbe, July 5, 1887, No. 366,193, and in which the connecting-arm for the compression-pieces or rolling-dies is placed between such pieces or dies and the gears.

My improved seal-press consists of only three parts-the two similar segmental c'ompression-pieces, each provided with similar guiding segmental gear and operating-handles, and the connectingstrip, to the outer ends of which the other two parts just described are pivoted the whole being arranged and operating substantially as-will be more fully hereinafter described and claimed. 4 In the drawings, Figure 1 is a front view of my improved press complete. 2 is an end view. Fig. 3 is a partial rear view. Fig. 41s a view of the seal before compression. Fig. 5 is aview of the seal; after compression, and Fig. 6 is a sectional view of Fig. 5, taken in the line a: 00.

Referring to the drawings, a a are the two similar segmental pieces,-the outer peripheries of which form the compression-surfaces a a. Extending outwardly from these segmental portions a a are the similar handles a? a employed in operating the press.

a a are the segmental gears, extending from-the handles a a in a plane parallel with the segmental portions 6 a, and having the open slots at a between the gears a a and portions of a.

The peripheries of the segmental gears a a and the segmental portions a a. are arranged concentrically, as shown, the radii of the gears a a being larger than those of the portions a (1-, their common centers being the pivotbolts 12 b, which extend across the open slots, a a and through the connecting strip or portion 0, by means of which the segmental gears a a and compression-pieces are loosely connected, as clearly shown in the drawings, the

connecting portion being located and operating within the open slots 0/ 01.

It will be observed that the similar parts of my press are so pivoted to the connecting portion 0 that the segmental gears a a intermesh and the segmentalcompression-s11rfaces a a remain at a certain fixed distance apart, such distance being. equal to the thickness of the compressed seal after it has been passed through the press, as clearly shown in Fig. 6.

It will be observed that the connectingpiece 0 is quite broad, thus serving to keep the operating parts of the press at all times in proper relation to each other while compressing the seal.

The lead seal 01, of substantially the shape shown in Fig. 4, is placed between the com pression-surfaces a a, at their contiguous ends, when the press is in the position shown in Fig. 2, and also in the dotted lines in Fig. 1. When in such position, the handles a o are swung together into the position shown in full lines in Fig. 1. As the handles a 01. are first moved in the compressing operation, the recesses c in the compression-surfaces a a serve to grip the lead seal and prevent it from slipping out, and, as the closing movement of the handles which perform the functions of joint-levers is continued, the seal d is gradually compressed until it assumes the fiat shape shown in Figs. Sand 6, after which it is quickly and easily liberated from the press.

The desired inscriptions'to be placed upon the seal are effected by raised letters or figures upon the compression surfaces 0/ a.

These compression-surfaces may be made of steel plates (shown at a a seated upon the segmental portions a a; but if cast-steel is used no plates are necessary. The segmental gears a a intermesh as the handles are being swung together or separated in the operation of the press, and serve,in connection with the pivoting portion 0, to keep the compression-surfaces a a in the same relative position during the compression of the seals, and, in fact, in any position of the lever-handles a Along the outer edge of one of the compressing surfaces a is placed the raised rib a, to confine the seal as it is being pressed within proper limits, so as to cifecta perfect compression.

It will be noted that my improved press is composed of only three parts, the two similar portions each composed of a handle, a segmental compressing piece, and a segmental In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
